AltoSignal vs BlueNote Communicator
BlueNote Communicator is a well-built Windows paging and "lights" intercom. AltoSignal does the same job with native apps for iPhone, iPad, Android phones and tablets, Amazon Fire, Mac, and Linux, plus a browser version for any computer, hosted in the cloud, so it isn't tied to Windows PCs on a single office network. A Windows app is on the way.
BlueNote Communicator Lights is capable software, color-coded light strips, timers, private conversations, and SMS alerts for medical and dental offices. Two things shape whether it fits your practice: it runs on Windows (it isn't macOS-compatible, and reaches Apple devices through a separate forwarding app), and it's hosted on your local network rather than the cloud.
AltoSignal takes the opposite approach: a web app that opens on whatever device your team already uses, hosted in the cloud so it works across rooms, buildings, and remote staff. If your office mixes iPads, iPhones, Macs, and PCs, or has more than one location, that's the difference that matters.

Not a Windows-only office? Run the same system on the front-desk iMac, the doctor's iPad, an Android tablet, and the PCs in back, no forwarding apps.
Hosted in the cloud, so it works across multiple locations and remote staff, nothing to host or maintain on your own network.
Every page is a clear "who · what · where" line with history and read receipts, so nothing quietly gets missed.
Both let a dental team signal each other without shouting. The main differences are platform and hosting: AltoSignal has native apps for iPhone, iPad, Android phones and tablets, Amazon Fire, Mac, and Linux, plus a browser version for any computer, and is cloud-hosted, with a Windows app on the way, while BlueNote Communicator Lights is Windows-only software hosted on a local network.
Yes. AltoSignal has native apps for iPhone, iPad, Android phones and tablets, Amazon Fire, Mac, and Linux, plus a browser version for any computer. A Windows app is on the way. BlueNote Communicator Lights runs on Windows and reaches Apple devices through a third-party forwarding app.
AltoSignal is cloud-hosted, so it works across multiple locations and remote staff. BlueNote Communicator Lights is hosted on a single local network.
AltoSignal is $3 per device per month, or $2 per device per month when billed yearly, a 33% saving. Paid plans have a 5 device minimum. The 30-day free trial does not, so you can start on as few as 2 devices, with no credit card. For 20 devices or more we offer volume pricing, so email sales@altosignal.com and we will quote you.
Yes, inside the office. Devices running the AltoSignal app on the same network hand signals straight to each other at the same time as the cloud, so your team keeps signaling with nothing to switch on. Changing button labels, adding a channel, or reaching a second location waits until the connection is back. The browser version does not take part in local delivery. See how local delivery works.
